DETAILED DESCRIPTION

[0018] See also Figure 1-5 The utility model provides a technical solution: a conveying device for emulsion explosives, comprising a cylinder 1, a pumping assembly 2 is arranged inside the cylinder 1, and a sealing assembly 3 is arranged at the lower end of the cylinder 1;

[0019] The pumping assembly 2 includes two fixed blocks 21, which are symmetrically fixedly connected to the outer wall of the cylinder 1. Hydraulic cylinders 22 are embedded in the two fixed blocks 21. The output ends of the two hydraulic cylinders 22 are fixedly connected to connecting rods 23. The other ends of the two connecting rods 23 are respectively fixedly connected to push rods 24 and pull rods 25. Sealing rings 26 are sleeved on the surfaces of the push rods 24 and the pull rods 25. The outer wall of the sealing ring 26 is embedded in the outer wall of the upper end of the cylinder 1. The lower end of the push rod 24 is fixedly connected to a push plate 27. A collar 28 is embedded on the surface of the push plate 27. The collar 28 is sleeved on the surface of the pull rod 25. The lower end of the pull rod 25 is fixedly connected to a pull plate 29. Two interfaces 210 are symmetrically fixedly connected to the outer wall of the cylinder 1.

[0020] The push plate 27 and the pull plate 29 are controlled to stop at the bottom of the cylinder 1, and then the push plate 27 is controlled to move upward. When the push plate 27 moves upward, a negative pressure space is formed between the push plate 27 and the pull plate 29, and then the emulsion explosive is extracted into the cylinder 1 through the interface 210 at the lower end, and then the pull plate 29 is controlled to move upward to push the emulsion explosive inside the cylinder 1 and output it through the interface 210 at the upper end. The push plate 27 and the pull plate 29 move slowly and will not affect the stability of the emulsion explosive.

[0021] The sealing assembly 3 includes a fixing ring 31, which is fixedly sleeved on the outer wall of the cylinder 1. Two through holes 32 are symmetrically provided on the surface of the fixing ring 31. Bolts 33 are inserted into the insides of the two through holes 32. The two bolts 33 are threadedly connected to the insides of two screw holes 34. The two screw holes 34 are symmetrically provided on the upper surface of the sealing seat 35. The sealing seat 35 is clamped on the bottom of the cylinder 1.

[0022] The bottom of the cylinder 1 is blocked by the sealing seat 35 to prevent leakage of the emulsion explosive. At the same time, the bolt 33 can be removed from the sealing seat 35, and the cylinder 1 and the sealing seat 35 can be separated, so that the components inside the cylinder 1 can be replaced and cleaned conveniently.

[0023] The push rod 24 and the pull rod 25 are symmetrically arranged inside the cylinder 1, and the push plate 27 and the pull plate 29 at the lower ends of the push rod 24 and the pull rod 25 are movably sleeved on the inner wall of the cylinder 1, so that the push rod 24 and the pull rod 25 can stably drive the push plate 27 and the pull plate 29 to move stably.

[0024] Two interfaces 210 are symmetrically provided on the outer walls of the cylinder 1 at the upper and lower ends, and the emulsion explosive is transported and flows through the two interfaces 210 .

[0025] The upper surface of the sealing seat 35 is provided with a convex block matching the opening of the lower end of the cylinder 1, so that the sealing performance of the lower end of the cylinder 1 can be ensured when the sealing seat 35 and the cylinder 1 are clamped together.

[0026] Specifically, when using the utility model, firstly, the two hydraulic cylinders 22 are staggered to start, and the two connecting rods 23 are pushed to move by the two hydraulic cylinders 22. When the two connecting rods 23 move, the push rods 24 and the pull rods 25 are driven to move, and the push plates 27 and the pull plates 29 are driven to move up and down by the push rods 24 and the pull rods 25. Firstly, the push plates 27 and the pull plates 29 are controlled to stop at the bottom of the cylinder 1, and then the push plates 27 are controlled to move upward. When the push plates 27 move upward, a negative pressure space is formed between the push plates 27 and the pull plates 29, and then the emulsion explosive is extracted into the cylinder 1 through the interface 210 at the lower end, and then the pull plates 29 are controlled to move upward to push the cylinder 1. The internal emulsion explosive is output through the interface 210 at the upper end, and then the push plate 27 and the pull plate 29 are controlled to move to the lowermost end of the cylinder 1, and then the push plate 27 and the pull plate 29 are controlled to move and transport the emulsion explosive. The movable push plate 27 and the pull plate 29 are relatively slow in the process of pushing the emulsion explosive for transportation, which can ensure the stability of the emulsion explosive during the transportation process. The push plate 27 and the pull plate 29 are not completely sealed from the inner wall of the cylinder 1. When the push plate 27 and the pull plate 29 are squeezed toward the upper and lower ends respectively, the accumulated materials at both ends of the cylinder 1 can be squeezed out, which can prevent a large amount of accumulated materials from remaining inside the pump.
